Curious why you say this when the linked article says the best thing you can do is avoid synthetic textiles

the article lists several things including textiles, plastic packaging, and avoiding tyre particles. I led with containers/bottles because that's where the most concentrated single exposures seem to be (microwaving in plastic, bottled water), but you're right that textiles are up there too, especially for airborne microfibres.

The exposure from food packaging is many times more prominent than polyester, which slows down leeching over time.

The article focuses on the airways. The commenter probably takes more hollistic approach and you are gonna eat way more palstic in yoir life than you breathe in.
